We are constantly looking at new hard drives, evaluating them for reliability and power consumption. The Hitachi 3TB drive (Hitachi Deskstar 5K3000 HDS5C3030ALA630) is our current favorite for both its low power demand and astounding reliability. The Western Digital and Seagate equivalents we tested saw much higher rates of popping out of RAID arrays and drive failure. Even the Western Digital Enterprise Hard Drives had the same high failure rates. The Hitachi drives, on the other hand, perform wonderfully.

In the second article they say that WD-RED are 2nd in reliability (WD-RED did not exist 2011). I'm happy that I've got a cheap Hitachi Ultrastar. But who knows.

As a personal anecdote: WD-Green failure rates are huge here. 24/7 Desktop machines, 240 drives. I've replaced in last 12 month at least 20 drives.

While WD has taken over Hitachi, they had to give Toshiba Hitachi's desktop 3.5" HDD operations in part of the deal of taking over Toshiba's (TSDT) Thailand factory. So if you want Hitachi's good 'ol reliability, buy Toshiba desktop drives.
